The objectof the invention is to provide an arrangement of frictiondraft gear for railway cars wherein is employed a; rear abutment or stopcasting secured to' the sills for preventing the forward movements ofthe friction shell. i

rlhe invention furthermore consists in the improvements of the parts anddevices and in the novel combinations of the parts and devices hereinshown, described or claimed. :in the drawing forming'a part of thisspecification, Figure 1 is a vertical, longitudinal central section of adraft rigging showing one embodiment of my improvements 1n connectiontherewith. Fig. 2 is a horizontal sectional `view of the structureillustrated in Fig. 1 and taken on the line 2--2 thereof. Fig. 3 is avertical, transverse sectional view taken substantially on the line 3--3of Fig. 1. And Figs. 4 and 5 are views corresponding respectively withFigs. 1 and 43 but illustrating `another em-v bodiment of the invention,Fig. 5 being taken onthe line 5-5 of Fig. 1.

1n said drawing, and referring to the structure illustrated in Figs. 1to 3, 10-10- denote channel center or draft sills ofv usual form, 11 adraw bar, 12 a cast yoke having ahooded forward end to which the drawbar is connected by a coupler key 13 slidably mounted in suitable slotsin the draft sills. Mounted within the yoke 12 is a friction draft gearof well known type desig-' rated generally byv the reference A.Extending between and connected to the sills at the rear of the gear Ais a heavy abutment or stop casting designated generally by thereference B.

L7llhe castingl B, as shown, comprises a front vertical stop face 14,parallel side walls 15-15 riveted to the sills 10, upper wall 16,reinforcing horizontal danges 1Y0- 170, and a forwardly extended, pref-.ated in the usual manner.

, cage.

erably integral arm or plate 17, the latter extending over the frictiongear for the pur ose hereinafter described.

T e gear A, as shown, comprises a combined friction shell and springcasing 18 with the shell at the rear, springs 19, and friction elements20, the latter bearing against the rear end of the yoke 12, the yoke inturn normally abutting, the vertical face 14- of the casting Bf ln bud',it is apparent that the yoke and inner element of the friction mechanismare prevented from movement by the casting B and hence as the frictionshell moves rearwardly the friction gear will be actuln draft, it isnecessary to prevent longitudinal movement of the shell 18 and for thispurpose, the arm 17 is provided at its front end with a pair oflaterally s aced, depending lugs or shoulders 21-21w ich coperate withcorrespending shoulders 22-22 formed in the upper face of the frictionshell and spring ln order to reinforce the shoulders 21, the arm 17 isprovided on its under face with ribs 23, 23, see Fig. 3. The gear andyoke are supported by means of a saddle plate 24 which is detachablybolted to the lower flan es of the draft sills by asucient number obolts to withstand a heavy pulling strain, three of such bolts beingshown in the drawing. Said saddle plate 24 is provided on its upper facewith a pair of upstanding lugs or shoulders 25-25, which also engagecorresponding shoulders 26-26 formed on the lower face of the frictionshell and spring casing 18. rlhe shoulders 25 are arranged opposlte theshoulders 21 so that the casting 18 is engaged at four points during thedraft actions of the gear. llt will also be noticed from Fig. 3, thatthe four lugs 21 and 25-form guides for the upper and lower arms of theyoke.

ln assembling the draft rigging, the friction gear is first laced withinthe yoke and then the yoke an gear are raised-vertically,

with the shoulders 22 of the casting 18 er1- gagin behind the shoulders21. Thereupon is provided with asingle, centrally located transverseshoulder 121 on its underface which coperates with a single upwardly ingdepending shoulder 126 which 1s arran ed 'to coperate with latransversely exten ing shoulder 125 formed on the krear edge of thesaddle plate 124. v In this construction, a horizontal yoke 112 isemployed 'instead of a vertical yoke and in order to support and guidesaid yoke, the saddle plate 124: is provided with upstandin flanges 40near each end thereof on whic the arms of the yoke reciprocate back andforth. The transverse shoulder 121 of the casting B is suitablyreinforced by longitudinally extendin ribs or anges 123. The' mannerof'assemb ing the gear illustrated in Figs. 4 and 5 will be obvious fromthe preceding description.

1. In a draft rigging, the combination with draft sills, of a earincluding a fric-4 tion shell between said sills, an abutment Kcastingat-the rear 4of the gear and secured to the sills, said casting havingan arm extended forwardly to overlap said shell, said arm and shellhaving coperating engaging shoulders arranged to prevent forwardmovement of the shell relatively to said casting under draft.

.2. In a draft rigging, the combination with draft sills, of aJgearincludin a friction shell between sald sills, an a utment casting at therear' of the gear and secured to the sills, said casting having an armextended forwardly to overlap said shell, said arm and shell havingcoperating engaging shoulders arranged to prevent forward movement ofthe shell relatively to said casting under draft, and' a saddle plateextending between the sillsbeneath the gear, said saddle plate andfriction shell having coperating'engaging shoulders to prevent forwardmovement of the shell under draft.

3. In a draft rigging, the combination with draft sills, of a gearincluding a friction shell mounted between said sills, an abutmentcasting at the rear of the gear and secured to said sills, said castinhaving a forward extension over the iction shell, said extension beingprovided with a depending shoulder, said shell havin a shoulder on itsupper side engaging the rst named shoulder on the rear side of thelatter to thereb prevent forward movement of the shell re atively tosaid casting under draft, and means for supporting the shell.

4. In a draft rigging, the combination with draft sills, of a gearincluding a friction shell mounted between said sills, an abutmentcasting at the rear of the ear and secured to said sills, said castingaving a forward extension over the friction shell, said extension beingprovided with a depending shoulder, said shell having a shoulder on itsupper side engaging the first named shoulder on the rear side of thelatter to thereby prevent forward movement of the shell relatively tosaid casting under draft, and means for supporting the shell. said meansincludin a saddle plate extending beneath the she said saddle plate andshell having coperating engaging shoulders also adapted to preventforward movement of the shell under draft.

5. As an article of manufacture, an abutment casting adapted to bemounted between and secured to draft sills of a car, said casting havinga vertical abutment face at its front end and a forwardly extendingintegral arm adapted to overlap a shell-like memberof a draft gear, saidarm having a shoulder near its front end adapted to c0- operate with ashoulder of said member to prevent forward movement of the latter underdraft.

In witness that I claim the foregoing I have hereunto subscribed my namethis 29th day of August, 1916.
